Anxiety over not finding a job?

I haven’t been sleeping well for the past few weeks bc I have been having lots of anxiety of job hunting and not being able to find a job. I’ve been out of work for only two months but have been to over 20 + interviews.

I feel like I’m doing everything well, been watching coaching videos, tailoring my resume/cv to the job’s description, showing enthusiasm during interviewers, asking lots of questions after the interview is done. I feel like I’m coming off as confident...I got good feedback saying i have great communication skills. I’ve made connections with the interviewers and follow up.

But why am I not able to find a freaking job?! It’s so frustrating. Could it be discrimination? Like I’m on the verge of having a breakdown bc I’m financially in crack. I can’t even get a simple customer service job.....

I’m in my early twenties and graduated from college also and had scholarships and a medic leadership experience. All of it.
